Hello,

I am working on a Vertical Axis Wind Turbine (VAWT). I want to do a dynamic simulation with pimpleDyMFoam. My problem is to define the interface between the static part and the rotating part. The rotating part is a cylinder around the wind turbine. I defined the faces of the cylinder as a wall with the tool "Named selections", called cylinder.

I don't know how to define the rotating zone after I converted the mesh in OpenFOAM. I have the AMI1 from the cylinder when I run createPatch but I can't create AMI2 (this boundary condition is empty).

I think I need to add this but I don't know where to write it and if it's correct :
Code:
AMI
{
faceType          boundary;
cellZone           rotatingZone;
faceZone          rotatingZone;
cellZoneInside  inside;
}
I read a lot of threads about this subject but I didn't find an answer to my problem.

Thank you for your answers,
Jacques

You can read the mesh in Fluent. Then it will create wall and wall shadow. You can write this case. Then use this case to generate openfoam mesh. Then polyMesh will contain both wall and wall-shadow as "wall" boundaries in boundary file. Now you can change these to AMI.

I couldn't do that because I don't have Fluent (I just have Design Modeler and ANSYS Meshing). Is there another solution ?

Best regards,
Jacques
